Activity : Complete the proof of the theorem.
Theorem: If measures of angles of a triangle are 45°, 45°, 90° then the length of each
side containing the right angle lis 72 x hypotenuse.
Proof : In A ABC, ZB = 90° and ZA-ZC=45°
.. BC = AB
Bb
By Pythagoras theorem
AB2 + BC =
AB2+ = AC ... (BC = AB)
.. 2AB2
Fig. 3.31
.. AB
.. AB 72 AC
This property is called 45°-45°-90° theorem.
